Abstract

Background: Airplane cabin supply air has been shown to contain multiple possible respiratory irritants. In addition, changes in barometric pressure in flight may contribute to specific respiratory conditions. Therefore, there may be an association between commercial airline flight and sinus disease. Methods: Participants of the Secondhand-Smoke, Air Quality and Respiratory Health Among Flight Attendants Study were administered an online questionnaire pertaining to their flight experience and respiratory health. Working years, working days per month, and number of trips per month were quantified, as well as smoking exposure and self-reported physician diagnoses of sinusitis, asthma, and rhinitis. The sinonasal outcomes were quantified using a Respiratory Questionnaire Survey (RQS) score. Multivariable analyses were performed to evaluate the associations between flight time and sinus disease. Results: A total of 579 participants met the inclusion criteria for this study, with cohort prevalence of sinusitis, asthma, and rhinitis of 25.3%, 14.4%, and 20.5%, respectively. Tertiles 2 and 3 of working days per month were associated with higher RQS scores compared to tertile 1 (p for trend <0.01). Individual symptoms significantly associated with increasing number of working days per month included "need to blow nose," "sneezing," and "thick nasal discharge," and the number of international trips per month was significantly associated with "coughing" and "facial pain and pressure," among other symptoms. Conclusion: This is the largest study to analyze the relations between airline flight time and sinonasal disease. The results suggest a possible association between sinusitis diagnosis, symptom scores, and specific sinonasal symptoms, and airline flight time.
